Integrated Ammonia Platform - Diesel Exhaust Fluid (DEF) Growth Project

Leveraging Integrated Assets to Supply Growing Regional DEF Demand

Project / Market Overview

Entered into a process design and licensing agreement to assess expansion of our integrated ammonia platform to supply the growing regional DEF market

DEF is an EPA-mandated additive for reducing NOx emissions from diesel engines, with strong

and growing demand driven primarily by Class 8 vehicle usage in the Mid-Atlantic and Northeast

Strategic

Advantage

AdvanSix's geographic position uniquely enables reliable, domestic supply to meet growing demand in a market currently served by domestic production from other regions and imports

Hopewell site already produces all required DEF inputs - carbon dioxide, ammonia, and high-purity water

Project designed with no expected impact to AdvanSix's ammonium sulfate fertilizer production

Timing and Returns

Final investment decision targeted for 1H 2027

Multi-year capital investment supporting attractive financial returns with anticipated operational start-up in 2029

Partnering with an established technology provider and engaging an engineering services firm to complete front-end engineering and design, project scoping, and cost estimation

Value Drivers Supporting Through-Cycle Profitability and Sustainable Performance

Durable Competitive Advantage

Portfolio Resiliency

Long-Term Positioning

Leading global cost advantage in vertically integrated caprolactam production - unique combination of assets and business model core to our advantage

Largely insulated from reciprocal tariff impacts with ~90% of sales in the U.S.; Anti-dumping

duties in place for ammonium sulfate and acetone in the U.S.

Industry actions now apparent with announced European capacity rationalization in phenol/ acetone and caprolactam/ ammonium sulfate as well as reduced China output

Ammonia and Sulfuric Acid platform integration coupled with leading technology position underpins SUSTAIN Ammonium Sulfate granular growth and DEF expansion

Product mix and asset utilization agility enable navigation through multitude of cycles

45Q carbon capture tax credits and tax legislation meaningfully benefit cash flow

Healthy balance sheet provides optionality for further value creation

Critical to supporting high utilization rates

Dedicated teams to improve effectiveness

Staggered across unit operations to maintain output

Proactive maintenance capex prioritized to mitigate risk and support safe, stable and sustainable operations

Primarily reflects the impact of fixed cost absorption, maintenance expense, and the purchase of feedstocks which are normally manufactured by the Company.

During the multi-site planned plant turnaround, additional required maintenance at our Frankford phenol plant contributed to reduced production across our integrated value chain and a delayed ramp to full operating rates at our Hopewell and Chesterfield sites, resulting in an incremental $15M unfavorable impact to pre-tax income, which is reflected in this amount and is inclusive of fixed cost absorption, higher maintenance expense and lost sales.

resulting in an incremental ~$17M unfavorable impact to pre-tax income, which is reflected in this amount and is inclusive of fixed cost absorption, higher maintenance expense, and lost sales.

Free cash flow is a non-GAAP measure defined as Net cash provided by operating activities less Expenditures for property, plant and equipment.

The Company believes that this metric is useful to investors and management as a measure to evaluate our ability to generate cash flow from business operations and the impact that this cash flow has on our liquidity.

The Company believes the non-GAAP financial measures included in this presentation provide meaningful supplemental information as they are used by the Company's management to evaluate the Company's operating performance, enhance a reader's understanding of the financial performance of the Company, and facilitate a better comparison among fiscal periods and performance relative to its competitors, as these non-GAAP measures exclude items that are not considered core to the Company's operations.
